Prototyping allows metal fabricators to transform theoretical designs into tangible, functional models. By creating a prototype, engineers and designers can evaluate the practicality and effectiveness of the design. This hands-on testing helps identify flaws or inefficiencies that might not be apparent in a CAD model.
A prototype of a custom enclosure for a data center can help verify its ability to handle cooling requirements, structural integrity, and aesthetic appeal. Catching these issues early reduces the need for costly modifications during full-scale production.
For projects requiring a high level of customization, prototyping is invaluable. Custom prototypes allow fabricators like DeWys Metal Solutions to collaborate closely with clients, ensuring the final product meets specific needs and expectations. It also fosters innovation, enabling manufacturers to experiment with new technologies, such as laser cutting, without committing to full-scale production.
At our US metal fabrication company, prototyping has allowed us to help clients bring unique, cutting-edge designs to life.
A physical prototype serves as a powerful communication tool between fabricators, designers, and clients. It bridges the gap between abstract concepts and practical implementation, giving clients a clear visual and tactile understanding of the final product.
This clarity builds confidence and ensures everyone is on the same page before production begins. Whether it&#;s a precision-machined part or a large structural component, a prototype assures clients of the project&#;s feasibility and quality.

Prototyping also helps streamline the production process by ironing out potential bottlenecks before full-scale manufacturing begins. With a prototype in hand, contract manufacturers like DeWys Metal Solutions can refine production workflows, identify potential issues in tooling, and optimize assembly lines. This preparation not only reduces lead times but also minimizes disruptions during production.
When fabricating a custom part, how often do you think about the process that created that design? Your customers are balancing many factors and are ultimately trying to bring a successful product into the world, regardless of the product&#;s mission. There&#;s a famous quote in the product design world, attributed to the design firm IDEO: &#;Enlightened trial and error succeeds over the planning of a lone genius.&#;
That&#;s a nice way to say that people are really bad at designing products. We get everything wrong: it looks bad; it doesn&#;t work right; nobody wants it; and maybe most important, you can&#;t make the thing.
In my world of software, we use an agile development process to ensure we create the right product. This means we frequently &#;ship&#; updates, gather data and feedback, and then iterate the design to improve the product. This entire cycle can happen in days or even hours.
For designers making a physical product, the cycles are much slower and more expensive. As a fabricator, you distinguish yourself by helping customers be more agile by offering reliable prototyping services, expediting options, and communicating effectively.
When it comes to product design, the biggest indicator of a successful product or technology is how quickly and how many times the development team iterates the design. Not only that, product designers need to think about not just form, fit, and function, but also how a product will be manufactured.
This is not a new idea; it dates back to the Bauhaus movement in the s. This was a German art school that basically invented modern industrial design. Their approach to design was to combine style, functionality, and mass production. They came up with iconic designs that still influence products today, ranging from chairs to teapots to lamps.
Eighty or so years later, this process was arguably perfected by Steve Jobs and Jony Ive with the iPod and first iPhone. Their countless rounds of prototypes helped them get key details right. For example, the overall size and shape was selected to ensure the device could fit comfortably in your pocket, and the layout of the controls ensured you could reach every button with your thumb. Without being able to physically hold and interact with prototypes made from the right materials, it would be impossible to nail that design. You simply can&#;t figure that out from reading a complex drawing.
Apple famously created a design lab to build great products, and it helped transform them into the incredibly successful company it is today. There were many portable digital music devices that made it to market, but the iPod was the only huge success.
Of course, not every product needs inspired design to succeed. In some cases, the most successful product in a category is the first to market. Designers are keenly aware of this and try to shrink project timelines to beat competitors. For these parts, a faster prototyping cycle might not be used to get additional design iterations, but rather to finish the project sooner.
So, what does this have to do with fabrication? Most sheet metal shops aren&#;t making consumer products or the latest tech gadget. But the same product design approach applies to OEMs in every industry. If we think like a product designer, we can help meet their needs.
greatlionparts are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
Iterative development makes the best products. Whether it&#;s an iPod or a sheet metal electronics enclosure, before you make thousands of something, you&#;re going to make a lot of prototypes. While some OEMs have internal prototyping capabilities, they struggle to staff those shops and keep them updated with the latest fabrication technology.
As a fabricator, embrace prototypes and prepare your shop to make them. You have multiple reasons for doing so. Prototyping is an important service for the sheet metal market, and customers are willing to pay for it. In fact, once the shop is set up to handle them effectively, prototypes can become your highest-margin work.
Delivering high-quality prototypes optimizes your chances of winning production work from new and existing customers. Building prototypes for important existing customers helps protect those customer relationships and prevents them from shopping that work to new vendors.
Top-performing shops often set up a prototype cell within the shop. The people working in the cell have a different mindset; they might not be able to make thousands of something, but it doesn&#;t matter. Prototypes require a different mentality and work best when staffed with dedicated people. A sheet metal mechanic with a sense of urgency will thrive in this role compared to a more detail-oriented production staffer.
The cell can have dedicated floor space and equipment, all set up to handle most parts made from your most popular materials. Even 1,000 sq. ft. or less can make an effective prototyping cell, when equipped with a small-form-factor laser, wet deburring machine, and highly automated press brake. Ordering precut sheets that fit on your laser removes the need for shearing.
Similarly, you can avoid a punch by allowing higher laser run times on these low-quantity jobs. Operations like welding, which are messy and require more space, can be handled by your production work center. When quoting prototypes that will require routing outside of this cell, be sure to add additional markup. That means at quote time, it&#;s critical to evaluate whether a prototype can be produced by your prototype cell. If not, you need to make a business decision about whether you want to quote that job based on the customer and how disruptive the work will be to your shop.
Another key to success with prototypes is to adopt a streamlined credit check process so you can accept jobs from new customers with minimal risk. There are many services available that make this painless and provide a quick response.
Many prototype buyers want to pay by credit card. Accepting credit cards reduces collection risk, especially if you charge the card when the order is placed or when you order materials. Uncertain charges like shipping or change orders can be collected in a second transaction when the order is complete. Check with your accountant for best practices and laws related to accepting credit cards for custom orders.
When engineers are shopping for prototypes, they&#;re less focused on price than most fabricators imagine. Lead time often is the most critical factor for prototype buyers. They want it fast, because if they can get it in days instead of weeks, or weeks instead of months, they get more design cycles and ultimately a more successful product. In fact, these buyers are in such a hurry that the job often goes to the first shop to provide a reasonable quote.
Prototype buyers aren&#;t buying bent metal&#;they&#;re buying time. You can profit from this, but only if you do it in the right way. When asked to quote prototype quantities, give more information. Quote the part at high quantities and long lead time and show off to the buyer how low the unit cost can really get. If you don&#;t have time to quote the volume production accurately, you can even mark the price as a nonbinding rough order of magnitude (ROM).
Next, quote their prototype quantities at your standard lead time. For many shops, this may be weeks or months out. Then, provide a quote for a shorter lead time, such as half that lead time or even shorter.
Even if you&#;re busy, put a price on it that if it was won, you&#;d be happy to let them cut the line. Even if you&#;re quoting double your standard price or more, it doesn&#;t matter. A lot of fabricators doubt this strategy until they try it. Think of it in this context: How much does it cost for a team of mechanical engineers to wait four extra weeks for a prototype?
Manufacturing is an extremely relationship-driven industry. Estimators and shop owners often get nervous about quoting higher prices for expedited jobs. They wonder what will happen if the buyer gets mad or thinks the shop is greedy. In reality, buyers crave market-based pricing for expedited service. The biggest custom parts manufacturers certainly provide these options. By assigning a value to an expedited lead time, you simply make it a business decision for the buyer. Is getting the parts earlier worth the fee? These options don&#;t hurt your relationships&#;after all, it&#;s not as if the buyer is personally spending their own money.
When quoting quick-turn jobs, also remember that the lead time on your quote matters too. We surveyed custom part buyers and found that about two-thirds of buyers expect quotes to be returned in less than 24 hours. This is even more critical for prototype work, where parts are expected in days to weeks instead of weeks to months. You might be wasting your time quoting a job days after receiving a request for quote (RFQ) because that job may already have been won by someone else.
There&#;s a big shift happening in the engineering world. The latest generation of product creators studied mechanical engineering or industrial design and bring a lot of interesting skills to their work. They&#;re also tech savvy and digital natives. But today&#;s engineers have never been further from the shop floor. All the time, we hear fabricators say things like, &#;Engineers used to know how stuff is made.&#;
Let your buyer&#;s lack of experience be your competitive advantage. You are the manufacturing expert. Experienced fabricators can quickly spot manufacturability issues from drawings and 3D models. This insight is incredibly valuable and can help improve a design without going through a costly and time-consuming prototyping cycle. Every quote is an opportunity to show a customer that you&#;re the person they want to work with. Buyers will realize you&#;re going to help them do their job better.
Embrace CAD, both when receiving RFQs and when providing a quote or feedback. An easy way to get started is to connect with a prospective customer over video chat and share your screen while viewing a 3D model. Shops that aren&#;t accustomed to quoting from 3D models are often surprised how many they receive by just asking for them. Let customers know they&#;ll get faster and better pricing and feedback when they send 3D models in addition to drawings or blueprints.
The shops growing the fastest today don&#;t necessarily have the latest and greatest machines; they&#;re the shops that are forming rich relationships with customers and leveling up to technology standards. When manufacturers meet designers where they are, that&#;s when business starts to really take off.
